Dassault Falcon 10X Completes First Flight: The Largest Cabin in Business Aviation Takes to the Sky

A Clean-Sheet Flagship Advances Toward a 2027 Service Entry

On June 19, 2026, Dassault Aviation's Falcon 10X lifted off from Bordeaux on its inaugural test flight, a defining moment for a program that represents the French manufacturer's most ambitious effort in a generation. The 2.5-hour flight, conducted by chief test pilot Sébastien Dupont de Dinechin and copilot Fabrice Dougnac, reached 40,000 feet and Mach 0.82 with no anomalies reported. The only new business jet to fly in 2026 has officially left the ground.

A True Clean-Sheet Design

Unlike previous Falcon evolutions, the 7X refined an existing platform, the 6X was a redevelopment of the frozen 5X program, the 10X is built from the ground up. New fuselage, new wing, a new digital flight control system, and twin Rolls-Royce Pearl 10X engines. Dassault has reset the design clock entirely for the first time in two decades.

The Cabin That Defines the Aircraft

The 10X's headline specification is its interior. At 9 ft 1 in wide and 6 ft 8 in tall, it offers the largest cross-section of any business jet in service or development, with approximately 2,780 cubic feet of cabin volume. For reference, the Gulfstream G700, its closest large-cabin competitor, measures 8 ft 2 in wide with around 2,603 cubic feet. The difference is immediately perceptible on board.

This is where Dassault intends to win the argument. With a projected range of 7,500 nautical miles, the 10X is highly competitive but trails the G700, G800, and Global 8000 by roughly 500 nm. The cabin, and the experience it enables on long-duration flights, is the aircraft's primary differentiator.

Key Specifications

• Cabin Width: 9 ft 1 in — widest in class
• Cabin Height: 6 ft 8 in
• Cabin Volume: ~2,780 cubic feet
• Range: 7,500 nautical miles
• Engines: Twin Rolls-Royce Pearl 10X
• Top Speed: Mach 0.82 (demonstrated on first flight)
• Estimated Price: ~$75 million
• Target Service Entry: Late 2027

Where the 10X Fits in the Large-Cabin Segment

The ultra-long-range segment is intensely competitive. The G800 and Global 8000 both advertise 8,000 nm range, giving them an edge on true edge-of-envelope missions. The G700 leads on speed and range within its class. The 10X's answer to all of them is the cabin, more usable space, more flexibility in layout, and a more residential feel on intercontinental legs where passengers spend 10+ hours aboard.

For operators who prioritize cabin experience over absolute range, the 500 nm shortfall on the longest routes is an acceptable trade. For clients running New York–Singapore or LA–Dubai nonstop, it will come into play.

Pricing at approximately $75 million positions the 10X in the same bracket as its competitors, making the cabin volume its clearest justification for the category.

What This Means for Our Clients

The first flight confirms the Falcon 10X program is advancing and that Dassault has a credible challenger at the top of the large-cabin market entering service in 2027.

For existing large-cabin Falcon owners (7X, 8X), this milestone provides a new reference point for used market values and trade-in timing. As the 10X approaches certification and early deliveries, buyer attention in the pre-owned segment will sharpen.

For buyers evaluating the ultra-long-range segment, the 10X adds a third serious option alongside the G800 and Global 8000. The right choice will depend on route profile, team size, and how the client weighs cabin volume against maximum range, a conversation Jetrock is well positioned to guide with independent, data-driven analysis.

As early delivery slots typically go to launch customers, those with genuine interest should be in dialogue with their advisors now.

Conclusion

The Falcon 10X's successful first flight is a significant milestone for Dassault and for the business aviation market as a whole. The program now has a flight-test campaign ahead of it before certification and a late 2027 service entry, but the hard part of proving the aircraft can fly has been accomplished. What enters service will be the largest-cabin business jet ever produced, backed by one of aviation's most respected engineering pedigrees.
